SPlNNlNG-MULE.

SPECIFICATION forming part of Letters Patent N 0. 727,349, dated May 5, 1903.

I Application filed February 6, I902. $erial No. 92,825- (No model.)

To (LZZ whom, it may concern:

Be it known that we, HENRY STAFFORD GOLLAND, merchant, residing at The Gables, Broad Oak Park, lVorsley, and JOHN DEM1 STER /VHYTE, engineer, residing at 108 Eurlington street, Manchester, in the county of Lancaster, England, subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Spinning-Mules, (for which we have made application in Great Britain, No. 13,913, dated July 9, 1901,) of which the following is a specification.

This invention relates to spinning-mules,

and has reference to improvements upon a former invention for which one of us, the said JOHN DEMPSTER WHYTE, has obtained Letters Patentiu the United States, Nos. 6O1t,593 and 652,203. I

The accompanying five sheets of drawings illustrate our invention.

Figure 1 is an end elevation of the improved yarn-guides and showing also the method of mounting the same upon the pokers. Fig. 2 is a side view thereof. Fig. 3 shows in side elevation the method of raising the pokers. Fig. 4 is an end View thereof. Fig. 5 shows in side elevation our improved method of reciprocating the yarn-guides. Fig. 6 is an end view of the same. Fig. 7 is a modified method of reciprocating the yarn-guides. Fig. 8 is an end view thereof. Figs. 9, 10, and 11 show on an enlarged scale the lever 18, fulcrum 19, and block 22, Fig. 9 being a side elevation, Fig. 10 a front elevation, and Fig. 11 a plan.

We will refer in the first place to the reciprocating inclines or yarn-guides for guiding the thread upon the spindles in Widelypitched spirals to produce a cross-wound cop and which relate particularly to the inclines described in Patent No. 652,203. In this patent the series of yarn-guides are reciprocated a short distance only, each thread having its separate incline or guide and being traversed up and down such guide. The arrangement of yarn-guides shown in Patent No. 652,203 is very suitable where cops with a short chase or small nose are being wound. Then it is necessary to increase the length of chase, we find in practice that an alteration in the construction of such yarn-guides is desirable. In the form shown in Patent No. 652,203 when the incline is advancing against the thread the thread is compelled to rise thereon from the base to the apex of the incline, or thereabout. On the incline receding the yarn slides down the incline for a portion of its length; but as it approaches thev thicker portion of the cop-nose the tension upon the yarn is sufficient to withdraw it from the incline, and being then no longer guided such tension causes the yarn to dwell and wind upon the thicker part of the cop-nose in one place, thereby shortening the chase. To obviate this defect,we provide each incline a with a slot b, extending from about midway in the length of the incline to the bottom. This slot may be obtained by placing parallel inclined surfaces closely together. The inclines are preferably stamped, pressed, or otherwise formed from sheet metal and provided with rounded edges 0 at the parts upon which the yarn bears to offer as little frictional resistance to the yarn as possible. These rounded edges are preferably covered with a highly-polished ductile metal, such as brass, or they may be coated with enamel or plated byelectrodeposition. Theyarn-guides may in some cases be formed from wire of suitable gage or molded in glass or made from other substances with suitable surfaces. As a result of the structural alteration in the yarn-guides when the guides are being traversed in the direction of the arrow, Fig. 2, the thread when it leaves the receding surface of its proper incline a comes at once into contact with the other side of the slot, which side is advancing, and is thus compelled to follow the contour of the guide to the bottom of the apex, or thereabout, so as to complete the desired chase. The chase of the cop can thereby be lengthened, avoiding the defect before stated.

The inclines or yarn-guides a are secured to a carrier a, which is a metallic bar of halfround section. The incline carrier at is supported by and slides upon the tops I) of the pokers, as will be understood.

Another part of our invention relates to the means for raising the pokers, to which the incline carrier is secured, and is illustrated in Figs. 3 and 4 of the drawings. In

the specification of the Patent No. 652,203 the poker-chains were secured to collars on a shaft which was rotated by means of wormgearing, and as the shaft was revolved the chains were wound thereon and the pokers therebyraised. We havenowinvented means to more perfectly synchronize the movements of the pokers and the winding-taller wire. To effect this, the worm-gearing is dispensed with, and we secure a chain (1 to each side of the nut 6 upon the screw-threaded shaft f. From the-nut e the chains d pass over guiding-pulleys g, and the other ends of the chains are wound upon pulleys h, carried upon the shaft 11 to be revolved. As the nut is traversed upon the screw-shaft not only is the winding faller actuated, but a pull is ind uced' upon the chains, gradually unwinding them from the pulleys on the shaft, and thereby revolving same. The method of actuating the nut e is the same as described in the former patent, No. 652,203, and is as follows: A pinion j, mounted to revolve in hearings in the bracket 70, carried by the mule-carriage m,

gears with a rack Z on the floor of the room,

so that as, the carriage m is traversed backward and forward the pinionj is rotated'in reverse directions. During the run-in of the carriage when the pokers are to be gradually raised motion is imparted by a bevel-wheel n, mounted on the axis of the pinionj, to a bevelwheel 0, which also is provided with a pinion 19, giving motion. to a spur-wheel q. Secured to the axis q of the spur-wheel q is a disk 7'. The disk 4" carries a pivoted pawl s, which catches against a lever t as the disk revolves and vibrates the same. The vibrating-lever t is provided with a pawl M, which actuates a ratchet-wheel o. On the axis of the ratchet-Wheel 1; is a pinion w, gearing with an intermediate pinion 0a, which meshes with a spur-wheel y, secured upon the screwthreaded shaftf. A slow motion is thus imparted to the screw-threaded shaft f, traversing the nut e, as required. The pawl s is mounted on the disk r to actuate the lever t only during the rem in of the mule-carriage, being idle during the run-out, as described in said former patent, No. 652,203. The pokers z are connected, by means of chains 1, to pulleys 2 upon the revolving shaft 11, as before. (See Figs. 5 and 6.)

In order to improve the formation of the cop-bottom, we provide means to cause the winding-faller and the pokers 2, which raise the yarnguides, to be raised slower at the commencement of the build of a cop than during the rest of the formation of the cop. To effect this, the shaper 3, through which the windingfaller is actuated and which rests on the nut e, mounted on the screwthreaded shaftf, is formed at the leading end with a concave surface 4, which by providing an increased area for the nut to travel retards the raising of the winding-taller un til the cop-bottom is formed. To retard the raising of the pokers 2, we provide the pul leys g with an adjustable stud 5, which act as cam-surfaces or increased diameter hearing upon the chains 61 when commencing to build the cops. The raising of the pokers z is thus retarded until the cop-bottoms are formed, by which time the nut e has by means of the chains (1, rotated the pulleys g so far as to remove the studs 5 from contact with the chains d. Fig. 3 shows the nut e about the commencement of the build of the cops, and Fig. 4 shows it at the end of the build.

To reciprocate the incline or yarn-guide carrier or, we provide a disk 6, which is revolved by means of a vertical shaft 7, receiving motion through bevel-gearing 8 from a horizontal shaft 9, driven by an auxiliary pinion 10 from the rack Z, secured to the floor of the room, as shown in Figs. 5 and 6. The disk 6 carries a crank 11, connected to a slide 12, mounted in bearings at 13 and 14, so as to provide ample bearing-surface and insure the slide moving steadily in a true horizontal path. The slide carries a rigid extension 15, arranged at the same incline as the spindles 16, upon which extension is mounted a sliding part 17, which is secured to the incline carrier ct. The slide 12 thus provides for the reciprocation of the incline carrier a, which is also raised and guided in the requisite inclined traverse by means of the pokers z and slide 17 as the building of the cop proceeds.

Another method of reciprocating the incline carrier a is shown in Figs. 7 and 8. In this method when forming the cop-bottom we commence with a minimum traverse of the incline carrier a and gradually increase such traverse, returning at each stroke to the initial starting-point of the incline carrier a. The stroke of the incline carrier is thus gradually lengthened until the cop bottom is formed, after which the lengthened stroke attained is continued throughout the building of the cops. Greatly-improved results are thus obtained in the formation'of the copbottom. We again employ a slide 12 with inclined extension 15, upon which is mounted a sliding part 17, secured to the incline carrier a, as shown in Figs. 5 and 6. The method, however, of reciprocating the slide 12 is varied. To efiect this object, we pro.- vide a lever 18, mounted on a slidable fulcrum 19, which is capable of sliding within the bracket 20. The slide 12 is connected by a stud 21 to the lever 18, the stud being secured to a block 22, capable of sliding to some extent within the lever 18, so as to compensate for the curved path described by the upper end of the lever 18. The lever 18 is vi- The stud 23 is guided and supported by a slide 23*. The fulcrum 19 is provided with a pendent rod 26, the bent foot 27 of which rests upon a stud 28, carried by a collar on the pokershaft '5. As this shaftt' is slowly revolved in the direction of the arrow the pendent rod 26 is allowed to drop, thus lowering the slidable fulcrum 19 of the lever 18. The throw of the stud 21 is thus gradually increased correspondingly, increasing the traverse of the slide 12, by means of which the incline carrier is actuated. WVhen the cop-bottom has been formed, an adjustable stud 29 comes into contact with a stop 30 or other fixed part of the mule-carriage 31, and thus limits the downward traverse of the rod 26, the fulcrum of the lever 18 being then stationary during the remainderof the build of the cop.
